Is more content better for SEO?

First of all, we can answer yes to that question. The more full your website is, the more likely your site will be in the top rankings of Google’s searches. However, it does not make any sense that the content you add to your website is copy and paste, which means that it is not original. You can enhance your site content in appearance by making copy and paste. However, because these content will not positively affect SEO, Google will perceive them as copy content. At this point, you should be aware that your content is as good and original as its number. Otherwise, all your work will be wasted. The content on your website is important to your Google Adsense application. Google will not respond positively to your application until it reaches a certain occupancy. At this point, it is also useful to be careful.

I can say that, this question is a bit complicated one. I could say that having more content on your website is better than having less. However, measuring the quality of the page by the number of content on the website is not a true way of thinking for SEO. The quality of your content is more important than the quantity. Your content should be an original one and should be SEO-friendly. If your content can not offer customers what they search on the internet, they do not have value for SEO.
Creating original content that gives information is really important for SEO. Having lots of content filled with random keywords won’t help you to rank higher on Google search results. SEO does not only mean keywords & content as most people know. However, you should also know that content is still important. You need to create content to have a successful SEO campaign. There could be articles, videos, images or other types of content at your website. Users should one what they look for on your website when they visit your website. Without content, it is not possible to have numbers of visitors. If you have lots of different content, and they are informative & original, your visitors stay longer at your website, and this is really important for SEO.
About the second part of your question, I can say that, it depends on the topic of your website. If you have a e-commerce website, your content should have pictures of the products that you sell. Having articles without pictures would not look good to your potential customers. They would probably want to see the products they are about to buy. However, if you have a website give information to people on how to become successful in SEO, you should have articles which are informative and extensive. You could also have videos and images about the topic to elaborate better. As you can see, it depends on the website.
So, If I need to summarize my answer, yes I can say that, more content helps you in SEO. However, you should know that the quantity of content is not more important than their quality. Your content should be original and they should offer information to people who visit your website. Having high number of content with lots of keywords will not help you in SEO.
